use AdinanCenci\Router\Router;
$r = new Router();

$r->add('get', '#home$#', 'controller');

// You may inform a single http method:
$r->add('get', '#home#', 'controller')

// Or several inside an array ...
$r->add(['get', 'post'], '#home#', 'controller')

// Or in a pipe separated string
$r->add('get|post', '#home#', 'controller')

// Or use an sterisk to match all methods.
$r->add('*', '#home#', 'controller')

$r->add('*', '#products/(?<category>\d+)/(?<id>\d+)#', function($request, $handler) 
{
   $category  = $request->getAttribute('category', null);
   $productId = $request->getAttribute('id', null);
});

$r->add('get', '#anonymous-function$#', function($request, $handler) 
{
    echo 'Anonymous function';
})

//-------------

->add('get', '#named-function$#', 'namedFunction')

//-------------

->add('get', '#static-methods$#', ['MyClass', 'staticMethod'])
// A single string also works:
->add('get', '#static-methods$#', 'MyClass::staticMethod')

//-------------

// Of course, it also accepts instances of Psr\Http\Server\MiddlewareInterfac 
// ( see the PSR-15 specification for more information )
->add('get', '#psr-15$#', $middleware)

//-------------

->add('get', '#object-and-method$#', [$object, 'methodName'])

//-------------

->add('get', '#object$#', $object)
// The ::__invoke() magic method will be called.

//-------------

->add('get', '#class-and-method$#', ['MyClass', 'methodName'])
// It will attempt to instantiate the class first.
// A single string also works:
->add('get', '#class-and-method$#', 'MyClass::methodName')

//-------------

->add('get', '#class$#', ['MyClass'])
// It will attempt to instantiate the class and call the ::__invoke() magic method.
